Walker Products Oxygen Sensor P/N:250-241273
Walker Products 250-24016 oxygen sensor for the 1995-1999 Ford Contour 4-cylinder 2.0L and other vehicles measures the oxygen in the exhaust gas so the engine computer can track combustion efficiency. It sits in the upstream position and sends the diagnostic feedback the ECU expects.
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can mean this sensor is worn, though damage to the wiring harness or connector can be behind them too, and both are worth a look for physical damage.
This sensor fits the 1995-1999 Ford Contour 4-cylinder 2.0L, the 1995-1999 Mercury Mystique 4-cylinder 2.0L and the 1999 Mercury Cougar 4-cylinder 2.0L. The listing is one upstream sensor, and each of these engines takes one.

Does Walker Products 250-24016 work as an oxygen sensor for the 1995-1999 Ford Contour 4-cylinder 2.0L?
Yes. Walker Products 250-24016 fits the 1995-1999 Ford Contour 4-cylinder 2.0L and goes in the upstream position.
Is this Walker Products oxygen sensor narrow-band or wide-band?
Narrow-band. Walker Products 250-24016 is a narrow-band sensor with four wires.
What protects the electrodes on this upstream oxygen sensor?
A coating covers the electrode surfaces to guard against contamination and erosion from combustion residue and particulates. The electrodes carry a gas-permeable platinum layer.
Which signs can point to this oxygen sensor being worn?
Rough running, higher fuel use, more exhaust emissions or a lit malfunction indicator light can. Newer vehicles store fault codes in the ECU, and a shop can read them.
Does the 1999 Mercury Cougar 4-cylinder 2.0L take one of these sensors?
Yes. The 1999 Mercury Cougar 4-cylinder 2.0L takes one upstream sensor, and this listing is one sensor.
